Hi,
Using Co:Z Launcher load balancing is currently an option for zBX users, only (via the Co:Z Load Balancer product).
Are there any plans to implement a Co:Z Launcher related load balancing mechanism for non-zBX servers (maybe by writing an own server state monitoring daemon or by using an existing Open Source monitoring solution like "Xymon systems and network monitor" - http://sourceforge.net/projects/xymon/)?

Any transparent load balancing product that allows you to define a VIPA for port 22 (SSHD) across the pool of servers should work.

If the load balancing product is not transparent, you may be able to use the Co:Z Launcher exit (just like the Co:Z zBX load balancer) to dynamically ask the load balancing product which real server IP to connect to.
